When I try to print to Roll, I sometimes get a "Paper Jam" error.
This may problem may have more than one cause, with sleep mode or a firmware problem perhaps linked to the problem. Probably the best answer was given by a poster on a Luminous Landscape Thread:
"I was having a terrible time using roll paper, and it turned out to be two mechanical problems:
(1) a white roller down inside the printer that was stuck down, due to a burr or some other snag, which a technician corrected by sticking a screwdriver down the back paper feed slot and pressing the side of the roller. It popped up, and he thought the problem was solved, since he had seen this before, and hadn't been called back.
Solving Problem 1 worked OK for the Canon Matte Coated paper and the Fine Art Bright White (after a struggle), but I couldn't get Canon Waterproof Canvas to load AT ALL. I tried to feed it in as far as it would go, but the paper wouldn't move or go into its back-and-forth roll paper load routine. Then the roll feeder would retract the paper completely and the printer had the audacity to say "Can't detect papr" [sic]. I called back the service technician, and he came out again. He determined that:
(2) the forward feed mechanism on the auto roll feeder wasn't working. The paper would retract, but not advance the paper. He took the auto roll feeder off, and we could hear something sliding around inside. I suggested perhaps a screw loose; he said it sounded more like a spring. He took it apart, and sure enough, it was a spring that was supposed to keep a gear in place that had come loose. He put the spring back in place, and it seems to be working fine so far.
All this was very frustrating, since I had already printed 20 or 30 feet on Canon Matte Coated roll paper without any problem. Then one morning I sent a print job and got the "Paper jam" message, then the "Can't detect papr" message when I tried to reload the paper. As soon as I inserted paper, the feed rollers on the auto roll feeder would clamp down and not move.
If it's working properly, you only have to feed the paper in just enough for the roll feeder rollers to grab it and the printer should take it from there. According to the technician, there is a slight curve in the paper path which might cause a problem if the roll paper has too much curl near the end of the roll.
I asked the technician about what happens if the leading edge of the roll paper isn't exactly square and he said the printer doesn't care too much about the leading edge -- that when it's checking paper alignment to prevent possible paper jams, it's checking the side edges of the paper."
